Abstract

The present invention relates to label inspection method in satellite MPLS network, using single-parity check codes to encode each node using the labels in label switch path of satellite MPLS network;the label switching router and label edge router in the network proceed parity check to the labels and discard packet with false label. The invention can effectively check label error caused by errorcodes of satellite communication environment in the label switch path of the satellite MPLS network, so as to reduce frequency of packet 'error insertion' in LSP and finally reduce LSP business loadcarrying properties loss. The invention is provided with advantages of simple implementing, good impacts and suitable for different label design methods, possessing wide application foreground.

Description

technical field

[0001] The invention relates to the technical field of satellite multi-protocol label switching technology MPLS, in particular to a label checking method in a satellite MPLS network. Background technique

[0002] In order to realize the seamless integration with the terrestrial network, the design of the satellite network gradually transitions to the framework of IP-based services. With the development of multi-protocol label switching technology MPLS (Multi-Protocol Label Switching) in the ground IP network, how to implement MPLS technology in the satellite application environment has become an important issue in the current satellite network research. Since there are differences between satellite wireless communication systems and terrestrial wired communication systems in terms of bit error characteristics, propagation delay, bandwidth resources, and equipment processing capabilities, it is necessary to study the impact of these factors on the implementati...
